Transmission of rotational movements – Basics of couplings

When shafts and axes are coupled in a machine, there is always a misalignment between the centre points of the shafts. The coupling compensates for this alignment error by the elasticity of the component or mechanical element during rotation or power transmission. Whether you are an experienced engineer or just diving into the world of mechanical engineering, this article gives you a comprehensive insight into the basics of couplings.
